Erlo Stegen emphasizes that God's ability to save is not limited, but our sins create a barrier between us and Him. The people in Isaiah's time were unaware that their disobedience was the reason for God's silence, believing instead that God had failed them. Stegen illustrates that sin is an affront to God's holiness and must be addressed for us to receive His help and guidance. He shares examples, including the Samaritan woman at the well, to demonstrate that acknowledging and confessing our sins is essential for restoring our relationship with God. Ultimately, the sermon calls for self-examination and repentance to remove the separation caused by sin.

A.B. Simpson expounds on Isaiah's vision of the future glory of Israel and Jerusalem, contrasting it with the current state of corruption and sin. He emphasizes the centrality of the Lord's house, which will be exalted above all nations, drawing people to God and establishing peace on earth. Simpson highlights the need for repentance and the transformative power of the Holy Spirit, reminding believers that a remnant will be saved and prepared for the coming glory. He encourages the congregation to hold onto the vision of hope amidst present darkness, assuring them that God's promises will be fulfilled.
